    1. to the change from books to articles and papers, whichleads to a large amount of duplication, and the ne-cessity of wading through a great deal of what doesnot interest us directly.

      Since 1908 there's also been the move towards small digestible social media which increases the dial on repetition and duplication, but the sense of flow created by dopamine hits to be found in the attention economy make these difficult things to overcome.

    1. 15:00 Before, we used to sit down with ourselves and process emotions. Now, we distract ourselves with technology.

      This aligns with my findings on taking more breaks and doing nothing in these breaks. This lessens dopamine spikes and gives space to have productive thinking. It engages more so the default mode network of our brains.

    1. 08:00 New information gives dopamine. Distraction arises from too many information that is goal irrelevant.

    1. 04:18 All flow triggers are either (a) reducing cognitive load, or (b) increasing dopamine or norepinephrine, that drive focus.

      Rian Doris people to first start reducing cognitive load. People are overwhelmed and feel like they can't take on new habits and tactics. He recommends to remove clutter from one's life. The more clutter we remove, the more time is left for flow.

    1. In both cases, it's up to us now to discipline ourselves to avoid the fats in junk food, and the breaking news and dopamine thrill-ride of social media.

      A nice encapsulation of evolutionary challenges that humans are facing.

    1. (14:20-19:00) Dopamine Prediction Error is explained by Andrew Huberman in the following way: When we anticipate something exciting dopamine levels rise and rise, but when we fail it drops below baseline, decreasing motivation and drive immensely, sometimes even causing us to get sad. However, when we succeed, dopamine rises even higher, increasing our drive and motivation significantly... This is the idea that successes build upon each other, and why celebrating the "marginal gains" is a very powerful tool to build momentum and actually make progress. Surprise increases this effect even more: big dopamine hit, when you don't anticipate it.

      Social Media algorithms make heavy use of this principle, therefore enslaving its user, in particular infinite scrolling platforms such as TikTok... Your dopamine levels rise as you're looking for that one thing you like, but it drops because you don't always have that one golden nugget. Then it rises once in a while when you find it. This contrast creates an illusion of enjoyment and traps the user in an infinite search of great content, especially when it's shortform. It makes you waste time so effectively. This is related to getting the success mindset of preferring delayed gratification over instant gratification.


      It would be useful to reflect and introspect on your dopaminic baseline, and see what actually increases and decreases your dopamine, in addition to whether or not these things help to achieve your ambitions. As a high dopaminic baseline (which means your dopamine circuit is getting used to high hits from things as playing games, watching shortform content, watching porn) decreases your ability to focus for long amounts of time (attention span), and by extent your ability to learn and eventually reach success. Studying and learning can actually be fun, if your dopamine levels are managed properly, meaning you don't often engage in very high-dopamine emitting activities. You want your brain to be used to the low amounts of dopamine that studying gives. A framework to help with this reflection would be Kolb's.

      A short-term dopamine reset is to not use the tool or device for about half an hour to an hour (or do NSDR). However, this is not a long-term solution.

    1. f learning makes new connections, then remembering that learning will strengthen those connections. As our brains create these structural changes, our thoughts produce neurotransmitters, a mixture of neurochemicals that create emotions.

    1. Google Scholar is needed to access annotations in context "Listen to the noise: noise is beneficial for cognitive performance in ADHD"

    2. The most intriguing result in the present study is thepositive effect of white noise on performance for theADHD children. This noise effect was present in boththe non-medicated and medicated children. Thissupports the MBA (Moderate Brain Arousal) model(Sikstro ̈m & So ̈derlund, 2007), suggesting that theendogenous (neural) noise level in children withADHD is sub-optimal. MBA accounts for the noise-enhancing phenomenon by stochastic resonance(SR). The model suggests that noise in the environ-ment introduces internal noise into the neural sys-tem through the perceptual system. Of particularimportance, the MBA model suggests that the peakof the SR curve depends on the dopamine level, sothat participants with low dopamine levels (ADHD)require more noise for optimal cognitive performancecompared to controls.

      Author's self-described "most intriguing result"

    3. The MBAmodel predicts that noise enhances memory perfor-mance for ADHD and attenuates performance forcontrols. We will also argue for a link between theeffects of noise, dopamine regulation, and cognitiveperformance.

    1. The dopamine reward system has also been shown to bestimulated by most drugs of abuse and plays an important rolein addiction [33]. An important question is whether jhanameditators are subject to addiction and tolerance effects thatcan result from stimulation of the dopamine reward system.

      The question of potential addiction to self-induced states that activate the dopamine (and/or other neurochemical) reward system(s) is important. From a more philosophical angle, should we welcome beneficial addictions that, if cultivated, might significantly improve individual and group quality of life? Isn't this related to our high regard for replacing detrimental with positive habits? Habit formation and maintenance also depends on activation of neural reward systems (see Nir Eyal's book, Hooked).

    1. Periodic Limb Movements of Sleep measurementsconfirmedthat ULDNallowed equivalent control of limb movements at half the prior dose of D2/3 agonists. Although the naltrexone dosewas 0.15 ug, the effect was retained at 100 ug and 1 mg(Bear and Kessler, 2014a,2014b).Thus, naltrexone proved effective forRLS, putativelyby facilitating sensitization of D2/3 agonists.

      The sources are patents. 2014a and 2014b.

      It is interesting that the benefits were retained over a large dose range. Oddly, full LDN doses (when combined with benzos) can help treat tardive dyskinesia. Thus, it seems plausible that the benefits for RLS are retained at even higher doses. I've not yet checked the sources to see if higher doses were tested. That is, doses over 1 mg. I doubt they were, because it would probably have been mentioned here.

    1. The next time, when you anticipate getting that new food, having that experience again, dopamine is now released in anticipation.

      Again, the brain has been trained that when you do this thing, you will get a reward. It's also interesting that the brain knows to release dopamine in anticipation of the event.

    2. You remember it. In the case of positive emotional memories, we think that the chemical dopamine is what's involved as marking them as survival enhancing.

      I think this is the first mention of dopamine specifically that I have come across in my research. Dopamine is released, you brain gets a reward, and remembers that this thing or action is good. It makes send that evolution would lead to this, so that survival actions are ingrained into the brain.

    1. serotonin has another function: It can act as one of those molecular Post-it notes. Specifically, it can bind to a type of histone known as H3, which controls the genes responsible for transforming human stem cells (the forerunner of all kinds of cells) into serotonin neurons. When serotonin binds to the histone, the DNA unwinds, turning on the genes that dictate the development of a stem cell into a serotonin neuron, while turning off other genes by keeping their DNA tightly wound. (So stem cells that never see serotonin turn into other types of cells, since the genetic program to transform them into neurons is not activated.)

      Serotonin can bind to H3 Histone and cause stem cells to become serotonin neurons.

      This research led the same team to wonder if Dopamine might act in a similar way.

      The serotonin paper is here: https://pubmed.ncbi.nlm.nih.gov/30867594/

    2. To put it plainly, the discovery that monoamine neurotransmitters control epigenetic regulation of genes is transformative for basic science and medicine

      Very bold claim to say that discovering that these neurotransmitters can induce epigenetic changes will transform basic science and medicine.

    3. To test that hypothesis, the researchers genetically modified H3 histones in rats by replacing the amino acid that dopamine attaches to with a different one it doesn’t react with. This stops dopaminylation from occurring. Withdrawal from cocaine is associated with changes in the readout of hundreds of genes involved in rewiring neural circuits and altering synaptic connections, but in the rats whose dopaminylation was prevented, these changes were suppressed. Moreover, neural impulse firing in VTA neurons was reduced, and they released less dopamine, showing that these genetic changes were indeed affecting the brain’s reward circuit operation. This might account for why people with substance use disorder crave drugs that boost dopamine levels in the brain during withdrawal. Finally, in subsequent tests, the genetically modified rats exhibited much less cocaine-seeking behavior

      Rats were genetically modified to decrease dopaminylation (modifying M3 so dopamine couldn't attach). This correlated to the Ventral Tegmental Area firing less (less cocaine impulse) and released less dopamine. This showed that these changes to H3, and subsequently the dopaminylation, did impact brain's reward circuit operation.

    4. dopaminylation. The term refers to the brain chemical dopamine’s ability, in addition to transmitting signals across synapses, to enter a cell’s nucleus and control specific genes

      Dopaminylation - Dopamine's ability to enter a cell's nucleus and control specific genes.

      CRAZY!

    5. they showed that the same enzyme that attaches serotonin to H3 can also catalyze the attachment of dopamine to H3 — a process, I learned, called dopaminylation.

      The same enzyme that helps serotonin bind to H3 can also help dopamine bind to H3.

    1. Look over your list. Do they contain words like published, awarded, graduated, built, founded or created? Or do they contain mostly adjectives like nice, caring, loving, honest and smart? If you’re in the first sentence it’s likely you’re an SC. If the majority of your responses are in the second sentence you are likely an RC.

      The difference is if listing egocentric stuff (I'm impressive and I feel better than others, I feel worthy for myself itself) or listing qualities that influence the surrounding world (I do social work to help refugees, I published a theory to improve the current state of philosophy, I completed a project or a school, I created something that now generates some kind of value).
